What kind of oil should be used in the manual transmission of Jiangling Transit?
3 Answers
This transmission has a relatively complex structure, so it requires lubricating oil that can adapt to turbocharged engines, specifically CF-4 grade or higher lubricating oil. Below is relevant information: 1. Transmission: A device that changes the speed ratio and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions are generally composed of a housing and several gear pairs. 2. Lubricating oil: Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It primarily serves functions such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.
For the manual transmission oil of the Jiangling Transit, I usually recommend using gear oil with a 75W-90 specification, preferably GL-4 or GL-5 grade. This type of oil ensures smooth gear operation, reduces wear, and prevents rust and corrosion, which is especially important for light commercial vehicles like the Transit that frequently carry heavy loads. Having driven similar models for many years, I’ve always used brands like Castrol or Shell, with good results. Remember to change it every 50,000 to 60,000 kilometers. When selecting oil, consider the vehicle’s specific year and mileage—newer vehicles may lean toward GL-4, while older ones are better suited for GL-5, which offers stronger anti-corrosion properties. If unsure, always check the owner’s manual first, as it contains detailed recommendations for the right model. Using the wrong oil might cause gear grinding or even premature transmission failure. The replacement process is relatively straightforward, but it’s best done at a professional shop. If the fluid darkens or develops an odd smell, it’s a clear sign to change it—don’t delay too long.
Choosing the right manual transmission fluid is crucial. For Jiangling Transit vans, it's best to use 75W-90 GL-4 or GL-5 gear oil. From my hands-on experience with numerous similar repairs, I've found that Transit transmissions are quite durable, but using incorrect fluid increases friction and causes gear shifting issues. For daily city driving, GL-4 works well, while GL-5 is more suitable for highway use or heavy loads. Don't skimp on brands - Motul or Total are reliable options. Remember to check fluid levels and change it regularly, typically every 40,000-50,000 km to maintain proper lubrication. The manual is always the gold standard - it specifies the required viscosity to avoid unnecessary repair costs from guesswork. When changing fluid, always clean the oil pan thoroughly to prevent contaminants from reducing transmission lifespan.
